For on-line internal quality inspection that is useful for non-destructively inspecting and measuring the internal quality based on the light information by detecting the reflected light that diffuses and reflects inside the object or the transmitted light that passes through the inside It relates to a transport device.

[0002] The objects to be inspected for internal quality include, for example, fish and shellfish such as pearl oysters and fish, meat of livestock products, and the like. This will be described in detail below.

[0003]

2. Description of the Related Art As means for measuring the internal quality of agricultural products using light rays, reflected light for projecting light rays including near-infrared rays to agricultural products and detecting internal quality information from reflected light from the agricultural products is used. System (for example, Japanese Unexamined Patent Publication No.
JP-A-7-229840) and a transmitted light system (for example, JP-A-7-229840) for detecting internal quality information from transmitted light in which projected light has passed through agricultural products. However, these methods relate to detection and measurement means including a light projecting device and a light receiving device for detecting internal quality information, and only one simple conveying conveyor is disclosed as the conveying means.

[0004] For this reason, the inventor of the present application has developed a tray for a sorter and an agricultural product sorting device as a transport means suitable for an internal quality inspection device, and disclosed it in Japanese Patent No. 2891973 and put it to practical use.

Further, a device has been developed which increases the amount of light projected on an object and projects it on a wide range of agricultural products, and can efficiently obtain internal quality information irrespective of size, item and type. Hei 11-173916 application, Japanese patent application Hei 11-2

As described above, according to the invention of each claim of the present application, the following effects can be obtained.

In the plurality of trays attached to the mounting bar, the interval between the trays at the start end on the entrance side is adjusted to the position of each row of the supply device supplied in a plurality of rows in the previous step. It can also be connected to such things. In the inspection section, the light emitting means and light receiving means necessary to inspect the interval between the trays adjacent to the left and right can be expanded to the space where it can be provided, so there is difficulty in light transmission such as the size of the object and the thickness of the skin Can also inspect the internal quality, gradually reduce the spacing between the strips toward the exit side, and at the end, the target can be sent out according to the spacing of the sorting conveyor in the next process, so multi-strips that can not be conventionally processed in large quantities An internal quality inspection device can be provided in the facility of the mold sorting conveyor.

Further, since the tray is guided and guided by a guide rail provided at the lower part of the traveling path, the starting end on the entrance side and the terminating end on the exit side are connected not only to the center of the frame of the embodiment but also to one side. There is an effect that can be applied to forming.

According to the second aspect of the present invention, since one mounting bar is provided with respect to the receiving tray and the space between the mounting bars is largely opened, the receiving tray is formed to have a low height therebetween, thereby stabilizing the object. There is an effect of being able to be conveyed and an effect of reducing the driving load of the conveyor.

According to the third aspect of the present invention, a hole penetrated in the vertical direction at the center of the tray serves as a transmitted light path, and the light receiving means provided near the bottom rear surface of the tray running at the inspection position of the inspection unit provides the transmitted light path. Since the transmitted light is condensed from the hole, even the slight transmitted light from the object can be detected without being affected by disturbance light. Since the amount of light is increased, it is possible to perform an internal quality inspection of an object through which light is hardly transmitted.

Further, the light-shielding bottom surface provided before and after the hole exit of the receiving tray serves as a shutter for closing the front light-receiving window of the condenser lens before and after the hole, thereby preventing the influence of disturbance light and preventing the environmental temperature of the spectroscopic analyzer and the like. Since the zero level due to the variation over time can be automatically calibrated, there is an effect that the continuous operation and operation can be performed for a long time.
